Filament reinforced tapes useful as underwater pipe wrap

Abstract

A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.

What is claimed is: 
     
       1. A method for constructing a member for undersea deployment is provided, which comprises:
 winding a wire reinforcement about tubular member(s); and 
 winding a seawater-resistant reinforced tape over the wire reinforcement, wherein the seawater-resistant reinforced tape comprises: 
 a polymeric film backing; 
 a layer of corrosion-resistant fiber directly adjacent one surface of the polymeric film backing; 
 a first pressure sensitive adhesive layer bonding the corrosion-resistant fiber directly to the polymeric film backing; and 
 a second pressure sensitive adhesive layer directly adjacent the first pressure sensitive adhesive layer; 
 wherein the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer comprise the same adhesive 
 wherein the corrosion-resistant fiber comprises glass, aramid, ultrahigh molecular weight (UHMW) polyethylene, polypropylene, carbon filament, or combinations thereof. 
 
     
     
       2. The method of  claim 1 , wherein the first pressure sensitive adhesive and the second pressure sensitive adhesive is selected from acrylic, silicone, synthetic rubber, natural rubber and modified acrylic formulations. 
     
     
       3. The method of  claim 1 , wherein the tubular member(s) is/are conduit(s). 
     
     
       4. The method of  claim 1 , wherein the corrosion-resistant fiber comprises polymer-coated E-CR glass, polymer-coated AR glass, polymer-coated S glass, polymer-coated E glass, and combinations thereof.
